DOOR-MAT.

SPECIFICATION forming part of Letters Patent No. 684,826, dated October22, 1901.

Application filed October 20, 1900. Serial No. 38,755. (No model) a newand useful Door-Mat, of which thefollowing is a specification.

This invention relates to certain new and useful improvements indoor-mats; and. the

object of the same is to provide a simple and effective device of thischaracter having structural features that render it exceptionally usefulin removing mud, snow, or ice thatmay become accumulatively caked on theshoe or boot, and which feequently resist removal by an ordinarybrush-mat, and also to produce a strong and durable mat of a flexiblenature and reversible, of a comparatively inexpensive character.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is a top plan view of a portion of one form ofthe improved mat embodying the features of the invention. Figs. 1, 1 and1 are similar views-of portions of the mat, showing different connectingdevices for the links. Fig- 2 is a detail perspective view of a portionof the one end finishing-strip of the mat shownin Fig. 1. Fig. 3 is adetail perspective View of a portion of the marginal strip for thedevice shown by Fig. 1. Fig. 4 is a detail perspective view of one ofthe links. Fig. 5 is a top plan view of a modified form of the improvedmat. Fig. 5 is a view similar to Fig. 5, showing the members of themodified form of the mat connected by different pivotal devices. Fig. 5is a view similar to Figs. 5 and 5 showing the members of the modifiedform of the mat connected by pivotal rivets. Fig. 6 is a detailperspective view of a portion of the marginal strip for the device shownby Fig. 5. Fig. 7 is a plan view of a complete mat havingsimilarly-arranged links.

Similar nu merals of reference areemployed to indicate correspondingparts in the several views. I

Referring to Figs. 1, 1*, 1 1, 2, 3, and 4, the numeral 1 designates aplurality of members or complete 1inks,of oval form,as shown,

or any other desired shape, and constructed from ribbon-steel ofsuitable strength and crimped to form longitudinally-extending centralprojections 2. These members have the central portions of the bodiesthereof to form transversely-extending barsconnected by rivets 3 oranologous fastenings, and the length of the said bars will depend on thenumber of the members fastened together andwhich will be. regulable atwill. The

projections 2 are apertured, and those formingthe terminals of one linkrespectively embrace or fit between the devices of a similar characterof adjaccntlinks and pivotallyconnected by short rivets 4, Fig.1,engaging each set of projections individually, or. by longer pins5,connecting two sets of said projections, Fig. l or by rods 6,oonnectingall the sets of a transverse series, Fig 1, or by rings 7,Fig. 1, the several different forms of connections in some instancesbeing used in one mat or individually throughout the entire matstructure, it being understood that any pivotal means will be employedto arrive atthe result sought. The edges of the members are exposed onopposite sides of the mat, thus making the latter reversible to increaseits wearing qualities, and in the use of thefsame the accumulations ofmud or other material from a boot or shoe and removed thereby fallswithin the confines or between the members, and thereby avoids cloggingthe same and facilitates removing the material thus collected by simplyraising the mat from over the same, and the open construction of themembers renders it easy to keep the mat itself in clean condition. Themembers or links 1 are formed of a single piece of the ribbon steel orstock or other suitable stock by doubling the same, as shown, andlatercrimped or doubled upon itself at regular intervals to formattaching projections 9, which are connected to the projections at oneside of the said outer or edge bar, the extremities 10 of the'said stripbeing bent in planes at right angles to the main portions of the sameand terminally riveted to the central portions of the end members of thesaid latter bar. This marginal strip strengthens the mat constructionand prevents the portions of the members connected thereto from beingcrushed down or from catching on articles passing thereover, such asdress-skirts and the like.

In Figs. 5, 5 5 and (i a modified form of the improved mat is shown andcomprises a series of bars 11, formed also from ribbon-steel and bent atintervals to provide trapezoidal loops 12, having the smaller portionsof one set fitted in and pivotally connected to the wider portions of anadjacent set, pivotal connection being obtained through the use of rods,pins, or rivets, and to completely close the one end or side of thisform of the improved device, as shown by Fig. 5, individual trapezoidalloops 13 are reversed and closely fitted in and secured rigidly to thenormally open loops of the bar at the side or end. The modified form ofthe device'just described also has two sets of working edges and is thusmade reversible, and in both forms of the device the bars are free tomove in relation to each other with obvious material advantage.

In both forms of the device in addition to the closing means along onemargin a movable finishing-strip is applied, as shown by Figs. 1, 2, 5,and (i, the said strip 14 in the first form consisting of a doubledpiece of suitable sheet metal gradually reduced toby a pivot-rod 16.These finishing-strips both permit the mat to be arranged close to asill or threshold or permit said portion of the mat to run downgradually to a floor-surface to avoid material projection and alsoprevent persons from stumbling thereover.

Many changes in the form,size, proportions, and minor details may beresorted to other than those noted without departing from the principleof the invention. 7

Having thus described the invention, what is claimed as new is- I 1. Amat of the class set forth composed of a plurality of links formed fromsingle pieces of stock and each intermediately bent to produce oppositesides continuous with each other and forming a closed end, the oppositeend of the link being open, whereby the closed ends of one series oflinks may be inserted in the open ends of an adjacent series of thesame, and means for pivotally connecting the engaged ends of the links.

2. A mat of the class set forth composed of a plurality of links made upof single intermediately-bent lengths of flat stock, the one terminal ofeach link being closed and the other open and both terminalstransversely reduced, the closed terminals of the links be ing fitted inthe open terminals of adjacent links, means for pivotally connecting theengaged link-terminals,,and means for securing the contiguous sideportions of the links to each other.

3. A mat composed of aseries of movablyconnected devices, and afinishing-strip pivotally connected to one series of said devices andconsisting of a single piece of doubled sheet metal with the edges ofthe inner side provided with structural means for connecting portions ofthe said series of devices thereto, and means for pivotally connectingthe said devices and strip.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
